 如果遇到默认 CDN 加载速度缓慢，可更换其他 CDN 镜像。以下为可供选择的公共 CDN，其中一些 CDN 可能需要数天时间同步最新版本：
 
-* `https://lib.baomitu.com/twikoo/1.6.36/twikoo.all.min.js`
-* `https://cdn.jsdelivr.net/npm/twikoo@1.6.36/dist/twikoo.all.min.js`

 > 建议使用 CDN 引入 Twikoo 的用户参考上一段的示例在代码中加入 [SRI](https://developer.mozilla.org/zh-CN/docs/Web/Security/Subresource_Integrity) 属性以确保完整性。
